quantity sold in thousands and p is the price in thousands. The
manufactures the product is planning to buy a new machine for the plant. There
are three options they can choose from. The cost function for each machine is
соmрaпy
shown below.
Machine A: C(x) =-4.1x + 92.16
Machine B: C(«) ——17.9х + 29.36
Мachine C: C(x) — —8.9х + 55.4
